I use a Tokonami KX450, which is not the newest but it's the most widely available military-grade model that the average silicon shop is able to customise.

With that in mind you'll want a uranium microreactor to really get that turbo button cranking out the keycodes (the french stuff is cheapest but ukrainian kit is worth the extra), as well as a mercury cooling solution and ideally a set of maglev keys for all the most common letters (NOT backspace; frankly you should remove that key entirely to avoid habits that damage your WPM).

Assuming you've got a solid pair of high-torque power gloves that should get you up to at least 20000 WPM, which admittedly won't cut it if you're trying to keep all the NPM dependencies up to date in a modern bank's transaction processing software, but it's probably enough if you're just doing a bit of data analysis in python.
